"failed to get i915 symbols" at boot (wiki solution don't work)

blno · 2012-02-11 16:18:16

Hello,

I've just installed Arch on a Dell XPS with a Intel i5(with an ATI card). It's a raw netinstall, I haven't installed anything else yet (only base and base-devel). A previous install of Arch used to run well on it a few months ago BTW.

I get a "failed to get i915 symbols, graphics turbo disabled" warning at boot. As the wiki says, I tried adding "i915" to the MODULES section of mkinitcpio.conf, and I get "*ERROR* drm/i915 can't work without intel_agp module!" at boot.

I've also tried to put "i915 intel_agp", "intel_agp i915", or even "intel_agp" alone as well. I've also tried to add "i915.modeset=1" to the kernel line in grub's menu.lst file.
Nothing works.

Of course I run "mkinitcpio -p linux" after each change.

What did I do wrong?

Thanks in advance.

If you have an ati card, then why are you playing with i915. There should be some setting in the bios to disable the intel graphics, and activate the ati one.

I'm not really sure. Windows works well in dual-boot, so I doubt the bios has something to do with it.

You're saying I shouldn't have to use i915 at all?

I've just tried to install xf86-video-ati (which used to work on an older install as well), and it doesn't change the error at boot.

Yep, if you're actively using the ATI card, then there's no reason to fiddle with integrated graphics. Either disable it in BIOS or blacklist the i915 module and your problem will be gone.

blno · 2012-02-11 17:23:11

Ok, so I've tried to blacklist it without results.

I tried adding "blacklist i915" to /etc/modprobe.d/modprobe.conf. I also tried doing it with both i915 and intel_agp, and finally I've tried "install i915 /bin/false".

I have the same "issue". I put it between "'s, because it's not really an issue. At least, for as far as I can tell. I'm happily using my ATi Mobility Radeon with Catalyst without problems and the warning (cause that's what it is) doesn't slow down my boot.

I don't know where it comes from, cause AFAIK my laptop (Acer Aspire 5740G) doesn't even have an integrated GPU. Also, none of the Wiki solutions have worked for me, so it's not something in your setup that is failing.

I'll be watching this topic!

That is strange, from my understanding if you blacklist a module, then udev should just forget that it exists and never load it, and therefore you shouldn't recieve any errors about it. Are you sure you don't have it set in modules array in rc.conf?

blno · 2012-02-11 22:41:03

I've just checked, and I don't have any module set in rc.conf.

Maybe Unia can try to blacklist it as well, to make sure I didn't make a mistake.

meph · 2012-02-11 23:44:09

From wiki:

Note: If you have a first generation Core i{3,5,7} series processor with an integrated GPU, failure to add i915 to the MODULES array in /etc/mkinitcpio.conf will likely cause the error kernel: intel ips [...]: failed to get i915 symbols, graphics turbo disabled.
Note: You may need to add the intel_agp module too if the system complains at boot time.

Indeed, I've done that (see my first post).

I've tried "i915", "i915 intel_agp", "intel_agp i915" and "intel_agp".

Ah sorry, misread that now.

One last idea I got after a bit of googling is to blacklist intel_ips as well. No harm done in trying that, not sure if it's going to help though, but it really is the last thing I could come up with.

jonnybel · 2012-02-15 02:54:13

I have the very same "issue", although it doesn't really seem to affect any performance at all. I already tried the same things that the OP did. However, it is a weird and ugly warning to appear always during boot and if someone else has already found out about a solution, please share.

Hi -- I have the same issue although my thinkpad does *not* have a discrete graphics card. It's just the i915.

Did you regenerate the initramfs after adding i915 to the modules? (using the "mkinitcpio -p linux" command in the terminal) if you don't run that command after adding i915 to that config file, it have no effect. Works fine here with intel graphics.

Hello

I've just got Arch up and running on my Dell XPS 15z (has a discrete NVidia card)

Not sure if this'll help, but here's my kernel's bootline:

kernel /boot/vmlinuz-linux root=/dev/sda1 ro logon.nologo quiet fastboot i915.semaphores=1 pcie_aspm=force i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 acpi=noirq

I hope some of that might help!
